I think Audi's look great, especially as you go higher end - RS4 / A7 / R8 - but they tend to be very mediocre about their low / mid range vehicles: A4 / A5.

I also agree with those who have said BMW is more innovative. I don't believe any CF has been used in Audi vehicles outside of the "blades" used on the R8, while BMW is making much headway with their partner (Callaway?).

Definitely agree on championship racing; Audi only participates in a few. ///M power is everywhere. ALMS is AWESOME to watch as they are the same cars we can drive, albeit with a few "slight" mods.
